I am searching for an explanation what exactly the output of the commands
ip link and
ip addr means on a linux box.
# ip link 3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000 link/ether 00:a1:ba:51:4c:11 brd ff:ff:ff:ff:ff:ff 4: eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT qlen 1000 link/ether 00:a1:ba:51:4c:12 brd ff:ff:ff:ff:ff:ff
What exactly are the
NO-CARRIER and other flags? I have found a reference at http://download.vikis.lt/doc/iproute-doc-2.6.32/ip-cref.ps but it does not contain complete information and man pages are not detailed enough.
